not mentioning any names here,

my bro told me once that there was this chinamen 'trick'.

the businessmen started gathering 'investment', with brilliant business and strategy and with so called back door connections with officials.

when it finally got all the money rolling in, he was telling that he was negotiating this and that, arranging this and that, even paid up a company in HK which provides ' fake company phone line ' service which provides office numbers and emails and even clerks to answer the phone calls, just in case the investors called in and check.

so eventually, after plenty of negotiation and all sorts of reasons and seasons this great businessman after 1 year told the investors that something went bust, and the plan cannot be continued, and he will refund all investors in full amount.

he did return all of it, the investors even wanted to invest again and guess what, officially, no con job happened
but guess what's the catch : he made a lot of money from by reinvesting the cash in stock market.

how to make money by using deception which is not illegal, perfectly logical from zero/nothing! 

and it's interest free
